I am putting together a spreadsheet for a Bowl Pick'Em league. I am trying
to have a column for confidence points that has a drop down list in each cell
with the option to pick from 1-34. I have figured out how to have a list
that allows you to pick from 1-34, but what I really need to figure out is
how to make it to where I can only select each number one time. For
instance, if I choose 7 in the first cell, when I go to the cell below it I
want to have the option to pick all numbers 1-34 EXCEPT 7. Is there a way to
do this?

As of now I have it set to DataValidate choose "list" then have the range
of cells showing a column that has the numbers 1-34.

Thanks for any help you might be able to give me.
